Professor John Zaller has developed "A Theory of Media Politics" that posits a system of political campaigns in which voters, presidential candidates and the media are dependent on one another (Zaller, 1998). This theory is a direct descendant of An Economic Theory of Democracy, (Downs, 1957) which portrays voters and candidates as rational actors. Zaller's theory expands Downs' model to includ...
Introduction: Mass media plays a crucial role in information distribution and thus in the political market and public policy making. Theory predicts that the information provided by mass media reflects the media’s incentives to provide news to different types of groups in society, and affects these groups’ influence in policy-making. A few empirical studies have tried to assess the effect of me...
Electronic properties for bcc Fe and hcp Co in bulk state and also Fe-Co alloy were calculated by quantum calculation based on density functional theory and pseudopotential method. Combination of Wannier function and Berry phase theory was used for calculation of anomalous Hall conductivity in above structures. It was seen that split of band by the spin orbit interaction, lying on the Fermi le...
With the advent of web 2.0, social networking sites (SNSs) have mushroomed. Gaining competitive advantage by retaining users in the SNS is an important issue for operators. By conceptualizing stickiness as the state of individuals’ prolong stay on the SNS, the aim of this study is to explore the process of formatting SNS stickiness in the context of Facebook from the perspectives of media richn...
The theory of crack propagation in orthotropic media is developed by applying the theory of incremental deformations in the vicinity of a state of initial stress. This is carried out in the context of a new approach to analytical methods and a physical analysis which takes into account plastic deformation under prestress. The state of initial stress is triaxial along the directions of elastic s...
Purpose: The aim of this study is to design a model of media literacy education in high school. Methodology: Since this research seeks to design a model or theory derived from the heart of data, so the data theorizing method of the foundation was chosen. To achieve this goal, with the opinion of the specialized council of the Book of Thought and Media Literacy, a practical case study was consi...
